Rainy season Nov–Mar: The Marrakech rainy season runs from November to March: that is when every tired terrace reveals itself. An ignored leak costs up to 10 times the price of waterproofing — damaged beams, lifted tadelakt, mould, repainting — and cuts the value of the property. The right time to waterproof is before the first heavy rain, not after it.

The Gueliz context
Gueliz, the new town laid out in the Protectorate era, is dense with 1930s–70s apartment buildings: ageing concrete slabs, technical roof terraces shared between co-owners, cracked parapets and original bituminous waterproofing that has often never been replaced. This is the district of co-ownership files: who pays, when to intervene, how to coordinate the top-floor flats. We manage the whole job there, from the shared diagnosis to the report for the building manager, with flame-free systems suited to occupied buildings. Gueliz summers regularly top 45 °C: black membranes baked by the sun crack open, and the first November rain exposes every defect.
We work in Gueliz every week: we know the local building types and we already know where to look for damp-proof wall injection — door thresholds, parapets, roof drains.

Trusted in Gueliz
“They re-waterproofed without demolishing: no rubble in the stairwell, a tidy site every evening. The neighbours noticed nothing.”
William G. · Gueliz“Our riad terrace was redone respecting the Medina’s constraints: materials carried in by hand, parapets rebuilt, zellige preserved. True specialist work.”
Sophie M. · Gueliz“Serious people: protection everywhere, deadlines kept, and the terrace handed back cleaner than they found it.”

It is the most profitable visit of your purchase: for a few hundred dirhams you know what the walls hide, with a written report that gives you real negotiating leverage — or saves you from a very bad surprise.
From 100 to 300 DH per linear metre of treated wall depending on the technique: injection 100–220 DH/m on concrete or brick, pisé-specific protocol 150–300 DH/m. A riad typically needs 15,000–60,000 DH of treatment.
Rising damp starts at ground level and climbs evenly (up to 1 m and more), often with saltpetre; a leak makes localised stains linked to rain. Our moisture measurements settle it in one visit.
Yes, with an adapted protocol: earth is neither concrete nor brick. Gentle injections or drainage depending on the case, and above all breathable finishes — never waterproof cement that traps moisture and destroys the wall.
